Plasma outflow from plasmasphere to magnetosphere (video)

This animation shows the Earth’s plasmasphere – the innermost part of our planet’s magnetosphere – and the plasmaspheric wind, an outward flow of charged particles. The doughnut-shaped plasmasphere is centred around the Earth’s equator and rotates along with it. The steady plasmaspheric wind continuously transfers material from the plasmasphere into the magnetosphere, releasing about 1 kg of plasma every second – almost 90 tonnes a day – into the outer magnetosphere.
